The expression “as such” has to refer to some status mentioned earlier. “The CEO was a former drill sergeant, and as such expected everyone to obey his orders instantly.” In this case “such” refers back to “former drill sergeant.” But often people only imply that which is referred to, as in “The CEO had a high opinion of himself and as such expected everyone to obey his orders instantly.” Here the “such” cannot logically refer back to “opinion.” Replace “as such” with “therefore.”
